COLLAR-BUTTON.

SPECIFICATION forming part of Letters Patent No. 650,455, dated May 29, 1900.

Application filed December 20, 1899. Serial No. 740,992. (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE W. DOVER, a citizen of the United States, residing at Oranston, in thecounty of Providence and State of Rhode Island, have invented certain new and useful Improvements in Collar-Buttons, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to that class of collarbuttons which are constructed without the use of solder.

My object is to produce a button of this class having a pearl head in such a manner that the head and body connection shall be effective.

The use of pearl as a material for the head of collar-buttons has been advocated because the rear surface of the head does not stain the engaged fabric, as do metal heads commonly employed; yet little or no progress has been made in this direction because of the seeming practical impossibility of attaching so fragile a member as a pearl head to a metal post permanently without fracture of the head. The construction and arrangement of the several button parts by which I attain the desired end are hereinafter described with reference to the accompanying drawings, wherein--- Figure l is a side View of the button-post; Fig. 2, a plan of the same; Fig. 3, a central vertical section of the button-head. Fig. 4 shows the parts assembled ready for engagement, and Fig. 5 is a central vertical section of the parts when finally engaged. Fig. 6 is a perspective view of the completed button.

In carrying out my invention I strike up a hollow button-post and base a in the usual manner and longitudinally split the top of the same, as at b h, as shown in Figs. 1 and 2. The back of the pearl head 0 has a circular counterbore d, the side 6 of the recess being shaped to resemble an inverted truncated cone whose base-line is broken bya pointed projection h in the center of the recess. This head is applied to the split top of the post,and ablock of lead or other soft and easilyepressed metal Z is inserted within the hollow post, as shown in Fig. 4. The parts thus assembled are brought into engagement by forcing the block Zthrough the tubular post into the recessed head by a plunger or other convenient mechanical means. Referring to Fig. 5 it will be seen that the upper surface of the block of soft metal on contacting with the projection h is forced outwardly thereby, expanding the split post-top and pressing the walls thereof against the tapering sides of the recess, thus so effectively uniting. the head and post members that separation is impos sible without fracturing the parts.

While my invention is primarily adapted to the construction of buttons with pearl tops, it maybe advantageously used when the head is composed of metal or other material.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A button comprising a hollow post having a longitudinally-split inner end; a head having an inwardly-flaring recess in its under side; and a block of softeasily-pressed metal filling the split end of said post and the portion of the recess not occupied by said split end and forcing the split sides into engagement with the flaring sides of the recess, the soft-metal block having a flaring inner end and holding the parts in close engagement with each other.

2. A button comprising a hollow post having a longitudinally-split inner end; a head having an inwardly-flaring recess in its under side with a centralv upwardly-extending projection from the bottom of the recess; and a block of soft easily-pressed metal filling the split end of said post and the portion of the recess not occupied by said split end and forcing the split sides into engagement with the flaring sides of the recess, the softmetal block having a flaring inner end and holding the parts in close engagement with each other.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE W. DOVER.
